WILLIAM H. F. RAIFSNYDER, OF OIL CITY, PENNSYLVANIA.

BULL-WHEEL FOR OIL-WELLS.

SPECIFICATION forming part of Letters Patent No. 233,373, dated October 19, 1880.

Application filed June12, 1880. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM H. F. RAIF- SNYDER, of Oil City, in the county of Venango, State of Pennsylvania, have invented a new and Improved Bull-Wheel to be used in Boring Artesian or Oil Wells, of which the following is a specification.

My invention relates to improvements in bull-wheels used in connection with oil or other wells; and it consists in certain details of construction, hereinafter fully described, and pointed out in the claim.

Figures 1 and 2 show an end view of my wheel and the manner in which the spokes are bolted or spiked on the shaft of the wheel, the shaft being notched to receive them. Fig. 3 is a side view of the wheel and shaft.

G G D show the construction of the rim by means of fellies spiked together and breaking The two outside fellies are a few inches larger than those in the center of the rim. This makes a wide groove on the outside or face of the rim. In this groove the brake works. E F show a narrower groove on the other wheel, in which the rope runs.

His a pin to which the ropeis belayed or made fast. This pin H is provided with an extension, the lower end of which is securely fixed to the huh-sections of the wheel B, and its upper end within and between the tellysections which comprise the rim of the wheel. This construction of the pin 11 prevents any liability of its being wrenched from its positions by sudden or unusual strains or shocks. By this construction of securing the pin H to a wheel, the rim of which consists of a series of thin ielly-sections-the first set being spiked on the spokes, and the next set notched over the ends of the spokes and breaking joints until the desired thickness of rim is obtained-a very desirable wheel is constructed, and one well adapted for the purpose for which it is intended.

I do not broadly claim the idea of constructing a wheel of a series of thin sectional fellies or arc-shaped rims, as something of that construction is shown by the patent granted W. J. McKee August 14, 1877, No. 194,162; but

What I do claim, and desire to secure by Letters Patent of the United States, is-- The wheels A B, constructed substantially as described, consisting of a series of thin felly-sections set over and around the ends of the spokes of the wheels, and having a pin, H, secured at one end to the hub-sections, and near the other end within the rim of the wheel, so as to allow of the pin projecting from the face of the wheel, all for the purposes herein set forth.

WILLIAM H. F. RAIFSNYDER.
